1:52 (Triple only) know how to represent a metallic lattice …

2019/6/21· 1:52 (Triple only) know how to represent a metallic lattice by a 2-D diagram. When metal atoms join together the outer electrons become ‘delocalised’ which means they are free to move throughout the whole structure. Metals have a giant regular arrangement of layers of positive ions surrounded by a sea of delocalised electrons.
